FIS-B lookahead for SUA Status
Votes
Answered By AOPA
While reading over the FDC NOTAMs, I saw this interesting entry come up:

AIRSPACE SPECIAL NOTICE..THE FLT INFO SERVICES BCST (FIS-B) SERVICE FOR OAKLAND /ZOA/ ARTCC AIRSPACE IS REDUCING ITS FIS-B PRODUCT LOOKAHEAD RANGE TO 5NM FOR THE SPECIAL USE AIRSPACE (SUA STATUS) PRODUCT. SUA STATUS INFO CONTINUES TO BE PROVIDED VIA THE FIS-B NOTAM PRODUCT. ALL FIS-B PRODUCT FORMATS REMAIN UNCHANGED. THIS UPDATE WILL OCCUR BTN 1400-1600 ON JUNE 11 2020.

Am I understanding this correctly to mean that SUA status sent over FIS-B will only cover a 5nm "hockey puck" around the aircraft? That seems incredibly small — you'd have to be practically on top of a piece of special-use airspace before you'd get any information about it.

Anybody know what the story here is?

Hi Trevor,

I didn't know what to make of the change either, so I reached out to our Government Affairs staff, and they in turn reached out to the ADS-B office at the FAA. Here's the response that we received:

The NOTAMs are going out as a notification to a change to one of the FIS-B products.  Here’s the rationale for the SUA product change:

SUA Status reports are also uplinked as D-NOTAMS. The FIS-B MOPS recommends that avionics process SUA status information from D-NOTAMS in lieu of this product to avoid confusion or conflicting information concerning SUA Status. The SUA product range is limited to 5 NM and this product will likely be eliminated in the future since the same information is available through a D-NOTAM.


So it appears that the range on the SUA status information has indeed been limited to the 5 NM "hockey puck", but this is because the information is also being uplinked from another source and they're attempting to negate any interference from the other source of the same information. I hope this helps.
